1. Twenty years ago rohan father was six times older than rohan. Let the present age of rohan father be x

then, present age of rohan be x/2

equation will be written as,

→x – 20 = 6 ( x / 2 – 20 )

→x – 20 = 3x – 120

→-2x = – 100

→x = 50 age of rohan father = 50 years

age of rohan = 25 years

Rohan age = 25 years

Father age = 50 years

Solution

Let the present age of rohan father be x

then, present age of rohan be x/2

Given

Twenty years ago rohan father was six

times older than rohan

equation will be written as

=> x – 20 = 6 ( x / 2 – 20 )

=> x – 20 = 3x – 120

=> -2x = – 100

=> x = 50

age of rohan father = 50 years

age of rohan = 25 years
